The SIR FF mode is selected by setting the module in the UART mode (UART3.UART_MDR1[2:0] MODE_SELECT = 0x0) and the UART3.UART_MDR2[3] PULSE bit to 1 to allow pulse shaping.
Because the bit format stays the same, some UART mode configuration registers must be set at specific values:
The UART mode interrupts are used for the SIR FF mode, but many are not relevant (XOFF, RTS, CTS, modem status register, etc.).
